    Abstract: The reinforced building structure which is lightweight, and working efficiency is preferable, and has a fire preventive performance and a decay durability, and can improve earthquake resistance strength without relying bracing. The structural building frame includes a pair of columns placed at facing in right and left, the upper horizontal member and the lower horizontal member jointed to each columns. The predetermined size of fiber reinforced cement siding 9 is installed in the structural building frame by horizontal boarding, and is fastens by nail 4 or screw by predetermined spacing.

    Abstract: A piezoelectric vibrator having three parallel vibrator arms formed from piezoelectric material in which dielectric polarization is generated through the application of electric fields extending widthwise between first electrodes formed on top surfaces thereof and between second electrodes formed on bottom surfaces, and also between the first and second electrodes through the piezoelectric material, such that a portion of the dielectric polarization occurs at the surfaces of the vibrator arms, and a portion also occurs within the vibrator arms. When ac driving voltages are applied to the electrodes, the vibrator arms vibrate at large vibration amplitudes due to strains created in the portion of dielectric polarization within the vibrator arms.

    Abstract: Described herein is a vibratory gyroscope. In the present vibratory gyroscope, two detection output portions are provided on a vibrator. The detection output portions are constructed such that an output (corresponding to a null output F0) obtained when no angular velocity is given, can be produced in phase and Coriolis output components F.omega.C and F.omega.D can be outputted in phase opposite to each other. Outputs C and D produced from both detection output portions result in the sum of vectors represented as F0 and F.omega.C and the sum of vectors represented as F0 and F.omega.D respectively. However, the sensitivity of detection of Coriolis force components can be increased by determining the difference .phi. in phase between the detected outputs C and D.
